Accents make everything better. Fact. Welcome to the Punch has a synopsis that sounds like most other movies:

Former criminal Jacob Sternwood is forced to return to London from his Icelandic hideaway when his son is involved in a heist gone wrong. This gives detective Max Lewinsky one last chance to catch the man he has always been after. As they face off, they start to uncover a deeper conspiracy they both need to solve in order to survive.

Then you realize that Mark Strong (Tinker Tailor Soldier Spy, Sherlock Holmes) is the antagonist and that Strong does that type of role exquisitely. Who will be the good cop to Strong's underworld titan? James "I'm Professor X, Bitch" McAvoy. Delicious,
